The Aputure LS 300d II is a daylight-balanced LED COB light designed for film, television, and video production. It is part of Aputure’s Light Storm (LS) series and has become one of the most widely used mid-power LED fixtures on modern sets.
The 300d II is commonly used as a key, backlight, or punch source for interiors and smaller exteriors, especially in owner-operator kits, indie productions, and rental packages.
Fixture Overview
The LS 300d II is a single-emitter LED COB fixture built around a daylight LED engine. It produces a hard, directional source that can be shaped with Fresnels, softboxes, lanterns, and projection accessories.
Compared to the original 300d, the Mark II version improved output, thermal management, build quality, and reliability, making it suitable for more demanding professional use.
Key Characteristics
Daylight-balanced LED COB light
High output for its power class
Bowens-mount modifier compatibility
Separate control box with battery support
Designed for location and studio use
The 300d II prioritizes flexibility and modifier compatibility over compactness.
Light Quality and Output
The LS 300d II produces a punchy, directional beam typical of COB fixtures. With modifiers, it can be used as a soft key, bounced source, or focused light for controlled applications.
Output is strong enough to compete with small HMIs in many interior situations and can hold its own outdoors in shade or controlled exterior setups when paired with a Fresnel.
Beam quality and softness are largely determined by the modifier used.
Color and Control
The 300d II is a daylight-only fixture, balanced around 5600K. It is designed to provide consistent white light rather than color effects.
Control options include:
Onboard control via the control box
DMX control
Wireless control via Aputure’s Sidus Link ecosystem
The control box supports AC power as well as battery operation, making the fixture useful for location work.
Mounting and Rigging
The LS 300d II features a sturdy yoke designed for standard stands and combo stands. The separate control box can be mounted to the stand or rigged nearby using the included clamp.
Its weight and size make it manageable for one-person setups, though modifiers and batteries can add complexity.
Typical Use Cases
Key light for interviews and interiors
Punchy source through diffusion
Lighting through windows
Bounce lighting
Small exterior or night setups
The 300d II is often used as a core workhorse light in compact lighting packages.
Where It Fits in the Market
The Aputure LS 300d II occupies the mid-range professional LED COB segment. It sits above entry-level LED lights in output and reliability, while remaining more accessible and portable than higher-power cinema fixtures.
It is most commonly used in:
Independent film and television production
Commercial and branded content
Owner-operator and small-crew kits
Rental-house mid-power LED packages
The LS 300d II is chosen when productions need a reliable, modifier-friendly daylight source that balances power, portability, and cost.
